Supplementary material for the research paper titled "Congo red dye removal using green synthesized titanium nanoparticles using saponin biosurfactant derived from Sapindus mukorossi"

The data presents the Congo Red dye removal efficiency using synthesized STiO₂ nanoparticles derived from saponin biosurfactant of Sapindus mukorossi. The study investigates the effect of varying adsorbent dosages (1, 2, 2.5, and 5 g/L) and different initial dye concentrations ranging from 50 ppm to 150 ppm. The experiments were designed to evaluate the adsorption capacity and efficiency of STiO₂ under these varying conditions. The results are compiled and presented in tabulated form.
